Description
Technical field
The utility model relates to pressure filtering technique field, is specifically related to a kind of high leakproofness feed arrangement of filter press.
Background technology
Traditional sheet frame class filter press, such as plate type pressure filter, adopts screw pump, membrane pump etc. to carry out charging more.
The advantage of screw pump is: 1) pressure and range of flow broad, pressure is about 3.4-340 kilogram/square centimeter, and flow can reach 100 cubic centimetres/point; 2) kind and the range of viscosities that transport liquid are broad; 3) because the pivoting part inertia force in pump is lower, therefore very high rotating speed can be used; 4) intake performance is good, has suction capacity; 5) uniform flow is continuous, vibration, and little noise is low; 6) compared with other drum pump, to the gas entered and dirt not too responsive; 7) sturdy construction, installs maintenance easily.
The advantage of membrane pump is: 1) owing to being used as power with air, so flow adjusts automatically with the change of back pressure (resistance to flow output), is suitable for the fluid of medium-high viscosity.And to take water as benchmark set in the operating point of centrifugal pump, if for the slightly high fluid of viscosity, then need supporting reductor or variable-frequency governor, cost just improves greatly, is also so same for gear pump; 2) reliable and cost is low with air driven pump in inflammable and explosive environment, as the conveying of fuel, gunpowder, explosive, because: the first, can not spark be produced after ground connection; The second, in work, empty calory produces, and machine can not be overheated; Three, fluid can not be overheated because the stirring of membrane pump to fluid is minimum; 3) severe in building site place, as the discharge of wastewater of construction site, industrial and mineral, due to the many and complicated component of the impurity in sewage, pipeline is easy to blocking, just forms the too high situation of load like this to electric pump, the motor feels hot rapid wear.Pneumatic diaphragm pump is by particle and flow is adjustable, automatically stops to unobstructed during line clogging; 4) can be used for the fluid carrying chemical property more unstable, as: photosensitive material, flocculation liquid etc.This is because the shearing force of membrane pump is low, little to the physical influence of material; 5) having in harmfulness, corrosive material process, material and the external world can separate by membrane pump completely; 6) or in some tests ensure there is no contaminating impurity raw material; 7) membrane pump volume is little is easy to mobile, does not need ground, and occupation of land face is minimum, simple installation economy.Can be used as movable object material conveying pump.
The feed pump more than enumerated is the pump that press filtration industry often uses, but spininess is to the material of moisture content 95%-99%, when material water ratio low to 60%-80% time, just need the special solid-state delivery pump of costliness to carry, current sheet frame kind equipment yet there are no and realizes charging in this way.The municipal sludge of such as low-water-content or seaweed mask raw material, in the use procedure of conventional feeds pump, loss is very large, and efficiency is extremely low.A large amount of idle running and fault this just cause huge power consumption and stand-by equipment.
Piston pump can solve above problem, but filter press itself needs the design of High Voltage charging, so feeding device of filter press needs the equipment using High Voltage, but use the feed arrangement of piston pump due to the volume in its pusher chamber be constantly change, relative motion between inboard wall of cylinder block and scraping wings, cause the hermetically-sealed construction life-span between inboard wall of cylinder block and scraping wings short, the hermetically-sealed construction damaged reduces production efficiency, increases maintenance cost.
